Amazing!!! It really is good! The seats do go back far to relax so if you don’t like the person to go back, just adjust and go back and everyone goes back to settle and be comfy. Enjoy few free drinks and the little amenities they provide.

Amazing!!! It really is good! The seats do go back far to relax so if you don’t like the person to go back, just adjust and go back and everyone goes back to settle and be comfy. Enjoy few free drinks and the little amenities they provide.

This Airline is really good! Better than Eva air for sure and more luxury. I really liked all the small details and amenities plus it really is free alcohol!

The crew services, the flight, the updates and our experience was awesome. Thank you.

Starlux is a great choice for long haul flights. It offers excellent foods and entertainment value. Ground staff are courteous, effective and efficient handing check-ins and understand travelers concerns. Flight attendants are equally great. They're full of positive attitudes and their goal is for traveler's getting destination with comfort and respect. Highly recommended.

Efficient boarding, on time departure. Cabin crew all nice looking and well dressed, helpful. Plane interior looked modern and new, fresh condition.

I thought all the while when I booked my flight I am entitled to check- in 2 luggages of 23 Kg each only to find out that the ticket I purchased online entitle me for only one luggage. I have been traveling for over 20 years and this is the first experience to such… so frustrating.

I was pleasantly happy with this airline, which is new to me. The crew was attentive and the seats felt better than most other economy. There was plenty of bin space. Glad I got to pick the seat I had(based on distance from baby image on seat map).

Business Class is a luxury that can be quite addictive. The priority and VIP treatment is great. We found a new favorite airline for our travels.

The meal and service were very excellent. It’s a n unforgettable journey

An excellent experience. The aircraft, crew, services, and amenities were all top notch for an economy class ticket. It has been quite a while since I've had this level of service on an airline.

seats are pitched well. you don't feel too tight.

For the price, it was better than other airlines; quality of food and service was very good.

Great but I am not sure why I was placed in zone 4 for boarding despite being an Infinity Member??? Can you explain online. Thanks

basic and only minimum of service, they offer nothing special

delayed and the cabin crew was like trainees.. a bit careless and not so pleasing to their job

The staff was marvelous. The entertainment options were terrible, old or 2nd rate movies. I was unable to entertain myself for 18 hours-it made it seem even longer. Note: I thought about upgrading but your information about what was included was unclear. Are the seats bigger? Are there current moves? What kind of food do you get? Would the upgrade compare to Delta? Just saying the upgrade is better didn’t convince me and I regret not flying Delta.

It was a good flight. I would highly recommend it to family and friends.

Plane is new and I was upgraded to first class so all was great.

On time service. Seat comfort and the crew service very good .

Only one Hindi movie from LAvto Taipei and same movie from Taipei to Singapore Really horrible and we call it entertainment???

Website from the 1990s, super frustrating customer support, inflight experience merely OK - more like United than e.g. Emirates

The seats are significantly more comfortable than US airlines and the staff are much friendlier. The food is also much better, as they are particularly accommodating to any dietary restrictions.

Could had been better if they include in their menu some western food.

They 7 seats in one row for Business class while most business class for other airlines are 4 seats in one row. the seat was narrow. the Toilet was so smell, dimming light, no water out of faucet. Terrible.

Difficult to access advanced check-in online. No way to understand why it wouldn’t work. Call center not answering. Email for answers took days to respond, Kind service at the airport and on the flight made up for disappointing service before flight.

There were agents in Haneda that assisted us with our short layover, they actually escorted us from plane to gate! Amazing service and kindness maybe eclipsed other minor issues. I had difficulty with on line check-in and because I wasn’t able to do it we had to go to the airport without advance checking. They split my friend and I in seating arrangement twice. Food quality and coordination of entrees and side dishes was a little off. Seat comfort led me to posture where I had to lean backwards a little unnaturally, from an upright position

Attentiveness by crew was very good. The seats were uncomfortable seemingly too hard with inefficient cushioning. This was verified with my traveling companions. Also the incline button was inoperable.

Courteous and helpful employees. Comfortable seats and temperature of aircraft . Did not need squid in my salad but glad to have the menu information advising me of what it was

Everything was great, except the Wifi, but that's understandable.

The plane was dirty, there was trash in the seat pocket in front of me.

So happy I flew with Singapore Airlines. The customer service is top notch. I am terrified of flying and the staff made me feel so at ease. Will only fly Singapore internationally moving forward.

It was very good experience on board to Sydney with SQ.

I very much liked and appreciated the service on board. The seating arrangement in Business feels uncomfortable. It's not made for tall people, in any case.

Great airline. Excellent service, good food & lots of TV movies/shows to choose from.

Everything was good except food , food choices was very less. Washrooms were closed.overall good experience.

Timing very good from sfo to Singapore and service was awesome and economy class seats are great overall very good experience thanks

Flight was delayed by baggage loading onto the plane. This was attributed to "inclement weather" (some moderate rain) which could be said to be beyond the airline's control, but the problematic part was that the plane was boarded and doors shut so that passengers sat in a cramped plane with rising temperature (full flight) for an hour. The airline was aware of the status of baggage loading, they could have deferred boarding to keep passengers comfortable.

This flight was 16 hours and they made it very tolerable. Seats were comfortable and the staff very accommodating. I had plenty of inflight entertainment. Food was very good.

Service excellent would chose Singapore airlines as my first choice

The staff were amazing and very kind. The seats recline a little too far back and are up close when sitting behind.

headphone jack didnt work for the first flight and not much variety

Delays took 2hours and thirty minutes making me miss my connecting flight and make me sit in the Chicago airport for 9 hours

Had a short delay once we boarded the aircraft in Chicago, but it was fixed in no time flat then we were on our way. The pilot was able to make up the time lost and we landed 5 minute later then schedualed . Great service

I had a bad experience with the security at IAH and felt like a sardine on all 4 legs of my journey.

Pilot Erika DeLong made us feel safe and at ease in a frankly scary time to be flying. Her warm smile and greeting and excellent command of the aircraft in foggy bumpy weather helped us all to calm our nerves and get us home safely.

Well, this is my second flight from THE first one that I took and this one was from Manila to Guam. The flight was comfortable. I did end up in first class. However, I had to fight for it a little bit, but when I went to Guam, I had to stay an extra night there, which was accommodated by united Which I'm pleased for that. The only thing that I have to say is when a situation happens with a cancelation. And you got first class guests very important that you accommodate and make sure that they have their flights before everybody else does, because we pay big money for the service and it is not cheap also. Take note There are things that we have planned as well. So this kind of damaged the tail end of my vacation, which I lost out in $2500 worth of car rentals hotel fair in Honolulu, Hawaii. I'm really hoping that I can be reimbursed at least that money from the insurance that I have on the trip through united. I will be submitting that in as well. When I'm back in the United States, because I'm currently in Guam. Staying good night. I'm waiting for my next flight out. For tomorrow morning..

I don’t understand the purpose of the orange “priority” tag on my bag. This tagged, my bag is last or near to the last bag to come down the carousel at IAH.

The tv monitor in front of my seat was not responding. The flight crew reset it and it still didn’t work.

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

Terrible. First of all we were delayed 4 3/4 hours departing Honolulu. As we had to leave our condo and the rental car had to be returned we had to go to the airport. Even though we had a business class boarding pass to Washington, since we did not have business class to Montreal we could not access the lounge without paying a $59 fee each. This does not make sense to us. Since we could not meet our original connection United booked us to Montreal via New York LaGuardia on Air Canada. In Washington a further delay got us into LaGuardia too late to make our connection to Montreal so we were booked on another Air Canada flight 3 hours later. We were originally scheduled to arrive in Montreal at 10:40 and arrived at 19:55. A totally exhausting day, United did not offer a meal voucher or any type of compensation. Air Canada did give us a digital meal voucher. The food in United business class is poor among all meals offered. The pods look nice but are not that confortable. Overall would not fly on United again.
